To all whom it may concern:

Be it known that we, ERNEST A. Rolnin'rs and NELS LAURENCE Jomvson,citizens of the United States, residing at Buhl, in the county of St.Louis and State of Minnesota, have invented certain new and. usefulImprovements in Electrical Hair-Singeing Devices, of which the followingis a specification, reference being had to the accompanying drawings. vI This invention relates to an electrical hair singeing device and hasfor its object to provide a handle member havin a head removably securedin one end, sai head carrying tubes adapted to receive suitable contact.members secured in a cap to connect an electric circuit and to heat awire loop, theends of which are connected to plates secured on the outerface or the cap.

Another object is to provide a very simple contact may be had at alltimes and the heating of the singeing wire absolutely assure 1 A furtherOb iect is toprovide means-for easily and quick y connecting theelectric circuit to heat the wire, said means being at- .tachableto theend of a cylindrical handle,

by means of which the device may be conveniently manipulated.

Withthese and other objects inview, the invention consists in thenovelconstruction,

combination and arrangement of parts, hereinafter fully described andclaimed, and illustrated in the accompanying drawings 111 p Which,

I ing Fi ure 1 is a side elevation of a hair-sin eevice constructed inaccordance with the resent invention; Fig. 2 is a vertical longitudinalsection thereof- Fig. 3 is a front end elevation; Fi 4 1s a transversesection on the line 4-4 in Fig. 2; Fig. 5 is a detail )erspective viewofthe removable head, and Fig. 6 is a similar view of the contact carryingcap.

Referrln to the drawing 5 indicates a substantial? preferablyconstructed of hard rubber, fiber or other suitable insulating material.This handle is hollow or tubular and is circum-.

ferentially enlarged at one end, as shownat 6. This enlarged end isprovided with 1nterior screw threads to receivethe reduced and areformed on the plates splitting their ends the secure y cylindricalhandle which is 'derstood t at it is not extension .8 of a removablehead7. Tubes each plate 10. These plates are d sposed upon the face of thereduced extension 8 of the head and are, secured thereon by means ofposed upon the same. This cap carries the contact rods 13 which extendtherethrough- 14 which are secured to the outer surface of the cap bymeans of the screws 15 threaded therein. The contact rods, 13 have theirouter ends split, as shown at 16 to secure a certain amount ofresiliency thereof. These rods are ada ted for insertion into the tubes9 dlspose through the head I, and by thus engagement of the rods withthe inner wall of the tubes is obtained. In this manner the proper conneetion ofthe electric circuit is assured. A

, wire loop 17 has eachof its ends secured to one of the plates 14.. Thecircuit wires which are incased in suitable insulating material areextended through an o in the rear endof the handle men; the terminalWires are "secured to the sepafplates' 10 arranged upon, the inner face6 the head 7 As the handle 5, head 7 and ca 12, are all formedlofinsulating material, it will be seen that the plates 10 and 14 areentirely insulated fromeach other and the electric circuit is connectedonly when the rods 16 are engaged in the tubes 9. The current may besupplied from an ening 18 er 5 and desired source of electro-motiveforce.

In the operation of the device, when the current is turned on and thecontact rods 16 are disposed within the tubes 9, the electric circuit isconnected through the wire 100 17- which soon becomes hlghly heated anmay be mani ulated by the operator to singe the hair in the desiredmanner. While this is the particular urpose' for which the device isrimarily a apted, it will be unimited to such use but is also applicableto many other desirable purposes.

In the manufacture of the device we con.- template providing the wireloops 17 in a the screws 11 which are threaded into; the; head. Theouter end portion of the head 7 is reduced in diameter and a cap 12 isdis-' multiplicity of forms each secured to a separate end cap 12. .Thuswhen another w re of diflcrent form may be found mofe dcfi sirable, itis only necessary to remove the cap and withdraw the rods 16 from tubeswhen the' electric circuit is disconnected. Another of the caps -car inga .dif-

ferently formed wire may then e inserted and the singeing operation:proceededwith. From the fore oing it will be seen that we have providea device which is-of very sim le construction and is admirably adapt Jed' or the urposesinview.

The ban le 5 ma be made in many other forms other than t at shown anddescribed, the essential feature of our invention residing in the mannerin which the contact is made.

lhe resilient end portions of the conttict rods 16 will compensate forthe wear which i is incident to the constant removal and insertion ofthe rods into the tubes, and insure the pro er connection of theelectric circuit where y the heating of the wire loop may be renderedabsolutely certain.

While the above descri tion sets forth the referred embodiment o ourinvention and is believed to be the one which is most de sirable in viewof the purpose for which the.

device is constructed, it will be understood that it is neverthelesssusceptible of various modifications in the form, proportion and minordetails of construction without materially departing from the essentialfeatures or sacrificing any of the advantages of said plates havingterminal wires of an electric circuit connected thereto, a cap disposedupon theouter end of said head, contact members carried bysaidcap'extending into said tubes, and a wire loop having its ends securedto said contacts and adapted to be heated by the passage of theelectrical current therethrough, substantially as and for the purposeset forth. s
